[H]ard|OCP was a little leery about the reappearance of Cooler Master's Game Xtreme series PSU after the first generations poor performance and even more so when they read the labelling on the new 650W model.  While it claims that its single 12V rail will power "the most demanding SLI/CF configurations", the 624W @ 52A maximum power rating is not up to handling multiple Titans nor does it help that there are only two 6+2 PCIe power connectors.  However it is not the PR that matters but how well it can compete against other PSUs with similar power ratings.  Once [H] hooked it up in their torture chamber it became clear that this PSU was not up to the job, about the only good thing they could spot was that it failed less tests than the first generation which does not count as a hearty recommendation.

"Cooler Master is a name synonymous with enthusiast computer desktop builds. You have likely purchased one if not more of its products in the past if you build your own boxes. The GXII line popped up on our radar recently, as we were seeing it on many brick and mortar computer store shelves, so we bought one to see what it is made of."

Cooler Master's new V-Series; good on the inside but perhaps lacking on externals

Subject: Cases and Cooling | July 28, 2014 - 02:25 PM |
Tagged: cooler master, V650S, modular psu, 650W, 80 Plus Gold

With a total rated power of 650W and two PCIe 6+2 power connectors the CM V650S seems to be aimed at entry level gaming systems but the $180 price tag suggests a high end PSU.  It is partially modular and it bears an 80 Plus Gold rating but perhaps the price also comes from Cooler Master's use of a new OEM, Enhance?  [H]ard|OCP did find it at a much more reasonable $80 on Tiger Direct but it is now out of stock and it does not seem to appear on NewEgg at all right now.   Overall there is a lot of good things to be said about the internals of the PSU but on the outside there is much left to be desired.  Check out the review but perhaps wait for the second version of the V650S before purchasing one.

"Cooler Master has been off the enthusiast radar in terms of computer power supplies for a while now. It simply walked a different line than much of the rest of the field. Today however we have one of Cooler Master's second foray back into the high end with a mid-level PSU rated for operation at 650 watts."

EVGA's 650W PSU, still sporting that strange handle

Subject: Cases and Cooling | June 5, 2014 - 12:52 PM |
Tagged: evga, EVGA SuperNOVA, 650W, NEX650G, 80 Plus Gold, modular psu

The EVGA SuperNOVA NEX650G Gold is a 650W PSU capable of delivering 20A on each of it's 12V rails with a maximum of 53A in total.  As it comes with four 6+2 pin PCIe power connectors and an extra 6 pin it should be able to handle multiple mid-range GPUs, though as [H]ard|OCP discovered it can get quite loud under full load.  As it can be purchased for under $100 it is a 'good enough' choice for many enthusiasts who don't need a kilowatt nor have a lot of money to spend.  It may not stand out in the crowd but it certainly passed every test [H] threw at it.

"EVGA does not have a lot to say about its SuperNOVA NEX650G Gold Power Supply. It does however mention it being designed with enthusiast needs, and this PSU being the "the best choice to power next generation enthusiast computers" with exceptional features, and stunning efficiency. We of course will be the judge of those claims."

Triathlor? Seriously Enermax?

Tagged: PSU, modular psu, enermax, TriAthlor, 650W

Platimax, Triathlor and NAXN; perhaps Enermax is not gifted at picking names for their PSUs but for the most part they are known for creating solid PSUs which do the job they are intended to.  Setting aside the name, this 650W mostly modular PSU has four 12V rails that combine to a peak of 54A, 648W which is certainly enough to power a modest multi-GPU system.  [H]ard|OCP put it through their own special brand of torture and were pleased with the results, a pass on all of their testing albeit results which trail the competitions offerings.  That keeps this PSU in the running as far as performance but at a current cost of $120 and perhaps higher in the future, it is hard to recommend this PSU over ones that do not cost as much and provide power of a quality at least equal to if not better than the Triathlor.

"Today we bring you an "athletic" power supply from Enermax that weighs in at 650 watts. The new Triathlor series sports plenty of features that enthusiasts will like including Silent Cooling, Flexible Cable Management, is marketed as being Rock Stable at All Loads. Enermax ads that, "The Triathlor FC is not a blinky poser."

Enermax replaces their MODU82+ series with ... Triathlor?

Subject: Cases and Cooling | March 1, 2013 - 04:12 PM |
Tagged: Triathlor FC, modular psu, enermax, 80 Plus Bronze, 650W

If you ignore the interesting choice of names, the Enermax Triathlor 650W looks good on paper with mostly modular cabling, an 80 Plus Bronze rating and a $120 price tag.  With four 6+2 PCIe power connectors and a pair of 30A 12V rails it will handle SLI/Crossfire of mid range cards but will probably have trouble with multiple flagship GPUs.  Hardware Secrets like the amount of available cabling and the quiet operation of the PSU but unfortunately they were not terribly impressed with the voltage regulation when it was run at full power.  Taking that into account, as well as the fact that similar PSUs tend to cost less than $100, they have difficulty recommending this PSU in the current market.

"The Triathlor FC is the latest power supply series with the 80 Plus Bronze certification from Enermax, coming to replace the MODU82+ series. So far, three models were released: 550 W, 650 W, and 700 W. Let's see if the 650 W model is a good buy."
